Which statement best explains whether y = 2x − 3 is a linear function or a nonlinear function?

It is a linear function because the graph contains the points (0, −3), (1, −1), (2, 1), which are on a straight line.

It is a nonlinear function because the graph contains the points (0, −3), (1, −1), (2, 1), which are not on a straight line.

It is a linear function because the graph contains the points (−3, 0), (−1, 1), (1, 2), which are on a straight line.

It is a nonlinear function because the graph contains the points (−3, 0), (−1, 1), (1, 2), which are not on a straight line.
